Beginning December 11, three new multiplayer maps will be available for players of Bungie's Halo 3 (X360). Titled the Heroic Map Pack, its three maps--Foundry, Rat's Nest, and Standoff--will be downloadable from the online Xbox Live Marketplace for 800 Microsoft Points ($10). Microsoft describes Standoff (pictured here) as "ideal for mid-sized objective and Slayer game types" due to its symmetrical layout and boulder-filled battlefield. Rat's Nest (pictured here) is said to be "an indoor vehicle paradise" best suited for big team battles, whereas Foundry (pictured here) is "the ultimate Forge map" as players can manipulate and replace every object object within it to create their own custom arena.
